SPECIFICATION forming part of Letters Patent No. 762,797, dated June 14, 1904.

Application-filed July 8, 1903.v Serial'No. 164,670. (No model.)

T0 all whom t mlrty con/cern,.- a

Be it known that I, HARRY J. BISHOP, a citizen of the United States, and a residentof J ersey City Heights, in the county. of Hudson and State of New Jersey, have invented anew and Improved Steam-Range, ofv which the following is a full, clear, and eXact description.l

My inventionrelates to improvements in steam-ranges especially designed for cooking and domestic purposes; and one'object that I have in View is to produce a simple and inexpensive structure wherein provision is made for heating bysteam an oven-chamber and a pluralityof cooking vessels, the supply to the several parts' beingV controllable at will.

A further object is to provide novel means for confining la removable vvessel "in steamtight relation to a steam-jacket which constitutes apermanent fixture of the'structure,Y

said vessel being so disposed as to permit access to be obtained easily to the contents:

thereof without disturbing the relation of the vessel to the steam-jacket.

Further objects and advantages will appear in the course of the subjoined description, and the novelty will be deiined by the vannexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of a steamrange constructed in accordance with my invention. Fig. 2 is a vertical section thereof on the line 2 2 of Fig. l, and Fig. 3 is a detail fragmentary sectional view illustrating another means for removably clamping a cooking vessel to a steam-jacket. a

The body or casing-A of the range isprovided in its front side with an opening adapted to be closed by an oven-door a, the latter permitting access to be obtained easily to an oven-chamber B. These parts may be of the usual or any preferred construction, and 'I do not consider it necessary to more particularly describe these features. The oven-chamber is formed by a shell b, and said oven-chamber is enveloped by a steam-jacket Owhich is arranged to form an intermediate steam-circulating space c with the shell b of the oven. The jacket C may be enveloped or lined with a non-conducting layer c of asbestos or' other suitable material, said lining c being applied either to the inner surface of the jacket C, as shown by Fig.` 2,v or to the outer surface thereof. The lining o of the oven tends to confine the heat within the chamber B, and the lining or jacket c serves a like purpose with relation to the steam-jacket O.

Steam is conveyed to the range by a feedpipe D,lwhich is shown as extending upwardly within the body-or casingvA. Said steampipe is provided with a branch d, having a suitable valve or cock d, said branch d being coupled to the steam-jacket O at any suitable point. As shown by Fig. 2, the branch 'd is'attached to the bottom part of the steamjacket C; but to prevent the water of condensation from flowing into the live-steam pipe D the branch d may be coupled to the steam-jacket at any suitable point above the lower portion thereof. The exhaust-steam and 'water of condensation are conveyed away from the oven by an exit-pipe E, the same being shown as disposed in parallel relation tothe pipe D and within the casing or body A. From this exit-pipe E leads a branch e, which is attached to the steam-jacket C for communication with the steam-space '0, and this branch pipe is provided with a valve or cock e', the latter being closed when steam is supplied to the space c for the purpose of heating the oven.

The body. or casing A is provided with a top plate F, the latter having a plurality of openings f. In Fig. 1 of the drawings I have sho'wn the top plate as having a series of four openings; butthe particular number of openings and the .size of the range are not material, because the structure may be made of any suitable size to accommodate any desired number of cooking vessels. j y

Each opening f of the top plate is occupied by a steam-jacket G, the same being suspended from the top plate F so as to lie practically in the upper part of the body or casing A. Each steam-jacket is contracted at its upper part, as at g, and provided with an annular ange g'. The contracted part -g of the suspendedjacket serves as a seat for the reception of a cooking vessel H, while the flange g of said jacket is arranged to rest on the-top plate F for the purpose of suspending the jacket in the manner described. It will be seen that the lower part of the suspended jacket G is of greater diameter than the seat part g thereof, and into this enlarged lower part of the jacket is extended or projected the lower part of the cooking vessel H, the latter being preferably of uniform diameter. The vessel is provided with an external shoulder 7L, which in the form of construction represented by Fig. 2 is inclined in order to rest snugly upon an inclined face g2 on the contracted part g of the suspended steam-jacket, whereby the shouldered vessel may be fitted tightly to the parts g2 and g of the steamjacket. The vessel is adapted to beheld firmly on the seat of the steam-jacket by any suitable form of clamping devices-such, for example, as the binding-screw L-and the described construction provides means for attaching the cooking vessel to the steam-jacket in a Way to secure a steam-tight joint between the cooperating parts. The vessel H is provided with suitable handles c' for its convenient manipulation, and said vessel may be equipped with a suitable cover or top. (Not shown.)

By reference to Fig. 2 it will be seen that the lower part of the vessel H is extended into the jacket G to produce therewith a steam space or chamber G', which surrounds the vessel H, at the sides and bottom thereof; but the upper part of this vessel H is extended above the jacket and the top F of the range, thus allowing ready access to be obtained to the contents of the vessel H without disturbing its relationship to the range-top and the steamjacket.

In Fig. 3 of the drawings I have shown another means for locking the cooking vessel to the steam-jacket. In this form of construction the jacket G is provided with the contracted portion g, and it is formed with a wide ange j, the latter being disposed for engagement with the range-top F. This iange is formed with a depression j', having an annular groove or channel f2, the latter opening upwardly. The cooking vessel H is provided with a laterally-extending iange L, having at suitable points a number of depending shoulders 7c', the latter being adapted to fit in the channel f2 of said wide Hange on the jacket G. One wall of the channel f2 is provided with a projection or stud Z, which is adapted to enter the groove that is formed in an opposing face of the shoulder c. The vessel H is adapted to be lowered into the jacket G for engagement with the contracted portion g thereofl and for the flange /f to engage with the flange j, after which the vessel is turned slightly to make the projection or stud l enter the groove in the dependent shoulder k, which occupies the channel of the wide fiange j. It isevident that the vessel can be' easily' turned in a reverse direction and lifted out of the steam-jacket, thus allowing said vessel to be readily placed in position and removed from the range without manipulating the binding-screw L. If desired, a suitablepacking may be employed between the jacket Gr and the vessel H.

The ran ge-top F is provided at its front edge with a flap or door I, and beneath this door are arranged the horizontal branches J J of the steam-pipes DE. The horizontal branch J of the feed-pipe D is provided with a number of other branches, K, which are connected with a series of steam-j ackets'G for the purpose of conveying live steam thereto, while the other branch, J has a like number of connections K with said series of steam-jackets for conveying the exhaust-steam therefrom. The branch pipes J J K K' are arranged below the flap or door I of the range-top, and these branches are provided with suitable stop-cocks L, the latter being readily accessible by the operator when the door I is opened for the purpose of admitting and cutting ofi the supply of steam to the steam-jackets G and for allowing the exhaust-steam to escape from the jackets into the exit-pipe thereof.

My improved construction provides means whereby live steam may be admitted to a steamjacket surrounding an oven-chamber and to a series of steam-jackets which envelop a like numberof cooking vessels. The supply of steam is controlled to the oven and the cooking vessels individually by the operation of suitable valves in the branches of the steam-pipes, and it is evident that any desired number of cooking vessels may be brought into service at the same time that the oven-chamber is employed.

In the practical service of Vthe apparatus I prefer to close the valve in the exit-pipe leading from the oven-chamber or other cooking vessel, while the valve in the feed-pipe is open to admit steam at the desired pressure to the oven or to the particular cooking vessel. When it is desired to discontinue the use of either vessel or the oven, the inlet-valve should be closed and the exhaust-valve opened, thus allowing the spent steam and water ofcondensation to readily escape from the oven-chamber or the Suspended steam-jacket.

It is evident that one or more of the cooking vessels may be removed, and in this event the steam-jackets should be closed by separate covers. These jackets are suspended from the top plate substantially Hush therewith, and when the cooking vessels are all removed another plate may be tted on or secured to the top plate F, so as to cover the steam-jackets and form a steam-table for cooking purposes.
